Not always. A medium-firm mattress is usually best for back support, since one that's too firm or too soft can both strain the spine and cause aches.

Your mattress is likely causing back pain if you wake sore but ease within an hour, sleep better elsewhere, or see sagging — these signs point to the bed, not your body.

Yes, a mattress can contribute to numbness by pressing on nerves or blood vessels when it's too firm or too soft, leaving limbs tingling. See a doctor too.

A mattress can contribute to neck pain by misaligning your spine, but your pillow is usually the bigger factor. Here's how both work together and what helps.
